Wholewheat pasta is a good source of complex carbohydrate and has a low GI value. Tossed with steamed summer vegetables and a fresh herb pesto, perhaps made ahead, this makes a tempting and satisfying meal.
Parmesan cheese is not truly vegetarian, as it contains animal rennet. To make this dish 100% vegetarian, omit the cheese or find a suitable vegetarian substitute made without animal rennet. In supermarkets look for the 'parmesan style hard cheeses' which are suitable for vegetarians.
For a more traditional pesto, use fresh basil leaves rather than coriander and mint. Flaked almonds work well as an alternative to pine nuts.
